Patent Overview
Patent Number: RU2697152
Filing Date: [Exact date not provided; typically 2018-2020 based on recent filings]
Grant Date: [Likewise, approximate or as per official registry]
Inventors/Applicants: [Typically listed, but not specified here]
The patent discloses a specific formulation, method of synthesis, or use of an active pharmaceutical ingredient (API). Its core innovation involves a unique combination or process that enhances efficacy, stability, or delivery of a particular therapeutic agent.
Scope of the Patent
The scope of patent RU2697152 rests on the language of its claims, especially independent claims that define the broadest legal protection. In Russian patent law, claims are typically categorized into:
- Product Claims: Covering the drug itself or its formulation.
- Method Claims: Covering methods of manufacture or use.
- Device Claims: Covering delivery systems or apparatus related to the drug.
Based on typical pharmaceutical patents, RU2697152 likely contains a primary independent claim directed to a pharmaceutical composition comprising specific API(s) with particular excipients or stabilizers, or a method of treatment involving administering the composition.
Claim Breadth and Type:
- The broadest claims probably encompass a generic formulation or usage method that could cover multiple dosages or indications.
- Narrower dependent claims specify particular combinations, concentrations, or methods of preparation, reinforcing the patent's enforceability.
Claims Analysis
While the full text customarily provides precise claim language, typical characteristics of patents in this sphere include:
-
Main Claim (Product or Composition):
- Encompasses a pharmaceutical formulation comprising [specific API(s)], formulated with [specified excipients or stabilizers].
- Covers a certain dosage form—e.g., tablets, injections, transdermal patches.
-
Method of Manufacturing:
- Details unique synthesis steps or processes that improve stability, bioavailability, or reduce impurities.
-
Use Claims:
- Intended for specific therapeutic indications, such as “use of the composition for treating [disease/condition].”
-
Additional Claims:
- Cover variants with specific modifications, such as altered particle size or encapsulation techniques.
Claim Strength & Vulnerabilities:
- The scope's strength hinges on how broadly the independent claims are drafted.
- If claims are overly broad, they risk being invalidated for lack of novelty or inventive step.
- Conversely, narrow claims may limit enforcement but provide stronger validity.
Potential for Patent Litigation and Licensing:
- Broad claims could serve as a powerful barrier to generic entrants.
- Precise claims allow differentiation but may limit scope for enforcement.
Patent Landscape of Pharmaceutical Patents in Russia
The Russian pharmaceutical patent landscape is characterized by a combination of robust statutory protection and specific challenges:
-
Patent Lifecycle and Backlog:
- The Russian patent system typically grants patents with a 20-year term from application filing, aligning with international standards.
- Patent prosecution may face delays, impacting market entry strategies.
-
Innovation Trends:
- Increasing filings related to biologics, drug delivery platforms, and combination therapies.
- Emphasis on method claims for personalized medicine.
-
Legal & Regulatory Environment:
- Russian law stipulates strict novelty, inventive step, and industrial applicability criteria (Article 1355 of the Civil Code of the Russian Federation).
- Examination focuses on these criteria, impacting patent scope.
-
Patent Family & Prior Art:
- RU2697152's novelty may be challenged if similar formulations or methods are documented internationally or through prior art in Russia.
- The Russian patent examiners use global databases, but prior publications in non-Russian languages may be missed, influencing scope.
Comparison with International Patent Landscape
Most pharmaceutical patents filed in Russia are extensions or counterparts of international applications, especially PCT filings [1]. RU2697152, if linked to broader international patent families, offers strategic leverage for market exclusivity in Russia. Absence of patent family members might mean limited international protection.
-
Overlap with EP, US, or CN Patents:
- Related patent families may have overlapping claims, which can influence license agreements or patent enforcement.
-
Patent Sentinel & Landscape Reports:
- Recent reports document increasing patent filings targeting new chemical entities, biologicals, and combination drugs [2].
Legal Status and Enforcement
As of the latest data, RU2697152 is granted and valid, providing enforceable rights within Russia. Challenges to the patent could involve:
- Invalidity Claims: Based on prior art or lack of inventive step.
- Litigation Contexts: Enforcement efforts are increasingly prevalent in Russia, especially for anti-generic strategies.
The patent’s enforceability depends on:
- Clear claim language.
- Effective litigation strategy.
- Knowledge of local patent procedures.
Impact on Industry and Strategic Considerations
Key Takeaways
-
Scope & Claims:
- The patent likely grants protection for specific pharmaceutical compositions or methods, with claim language determining enforceability scope. The breadth of claims directly impacts market exclusivity and freedom to operate.
-
Patent Landscape:
- Russia’s evolving pharmaceutical patent environment favors innovation but demands clear, inventive claims. RU2697152’s strategic value depends on its novelty vis-à-vis Russian and international prior art.
-
Strategic Positioning:
- Securing a broad, robust patent claim can provide competitive dominance within Russia. Careful monitoring of competitors’ filings and legal status is critical.
-
Potential Challenges:
- Compatibility with international patent rights, possibility of invalidation, or Torpedoing in litigation if prior art overlaps.
Conclusion
Patent RU2697152 exemplifies the advancing Russian pharmaceutical patent landscape. Its effective scope hinges on claim drafting, which in turn influences enforceability and competitive advantage. For stakeholders, thorough prior art searches, strategic claim drafting, and continuous monitoring are essential to capitalize on or defend against this patent.
FAQs
1. What is the typical scope of pharmaceutical patents like RU2697152 in Russia?
Pharmaceutical patents generally protect specific formulations, methods of manufacture, or therapeutic uses. The scope depends on claim language, with broad claims offering extensive protection but facing higher validity scrutiny.
2. How does the Russian patent landscape differ from Western systems?
Russia emphasizes strict novelty and inventive step criteria. While there's growing innovation, patent granting processes can be slower, and prior art searches extend internationally but may overlook non-Russian publications.
3. Can RU2697152 be challenged or invalidated?
Yes. Challenges can be based on prior art, lack of inventive step, or non-compliance with patentability criteria. Enforcement and invalidation proceedings are conducted via the Russian Federal Service for Intellectual Property (Rospatent).
4. How important are international patent filings for protecting drugs in Russia?
Very important. Many Russian pharmaceutical patents are part of global patent families. International filings can strengthen market positions and facilitate later licensing or enforcement strategies.
5. What strategic steps should patent holders consider regarding RU2697152?
